VIERA, Fla. -- The Mariners worship at the throne of Felix Hernandez, because for them, he is The King, the centerpiece of their franchise. There's nothing more they want than for Hernandez to thrive, and for this, they'll pay him, happily.

But they'll have to work through some concerns about the elbow, whatever the specific nature of those concerns, and this is just the latest example of an industry trend.

As the dollars invested in salaries grow, and they become more precious in the draft system, teams have become more and more careful about reviewing players' medical records -- and, in the eyes of some agents, becoming more apt to throw up red flags.
